Smoke in the Cabin at 2 a.m. on a Rural Stretch
You are driving a 56-passenger coach on a rural two-lane highway at 2:00 a.m. with 41 passengers, many asleep. You smell an acrid electrical odor, then see faint smoke curling from the panel near the entrance door. There is no shoulder for 300 meters; the road has a narrow gravel verge and a ditch beyond it. The nearest town is 11 km ahead. A passenger has already stood up and is shouting. Your fire extinguisher is mounted behind the driver's seat. The coach has a rear door and roof hatches.
1. Walk through your immediate sequence of actions from the moment you confirm smoke, and justify the order.

Confirm and act, do not investigate while driving. Signal, slow smoothly, and get the coach off the travel lane onto the widest available verge, even if that means stopping short of a perfect pullout; a coach stopped in a live lane at night is its own hazard, so use hazard flashers and, if equipped, reflective triangles once stopped.
Order: stop, set the parking brake, shut off the engine and master electrical switch if the smoke source is electrical, then evacuate. Evacuation comes before extinguisher use when smoke is in the cabin, because smoke is the killer and the extinguisher is for a small fire you can reach with your exit behind you. Direct passengers out the rear door and away from the coach, upwind and off the roadway, and account for everyone by a head count against your passenger count. Only then, if the fire is small and contained, attempt extinguishing from a position with a clear escape path; never re-enter a smoke-filled cabin. Call 911 with your location, mile marker, and passenger count.
2. A passenger insists on going back for a laptop, and another wants to stay on the bus because it is cold outside. How do you manage both, and what changes if the smoke is coming from a wheel well rather than the panel?

Both requests get a clear, firm refusal. Nobody re-enters for property; the coach is replaceable and people are not, and a returning passenger becomes a second victim you must now rescue. For the cold, the answer is distance and warmth in numbers: move the group upwind and away from the vehicle, share coats and blankets, and keep people together where you can see and count them. Give them a task (calling family, watching for traffic) to reduce panic.
If the smoke is from a wheel well, the risk profile shifts: a dragging brake or overheated bearing can ignite a tire, and tire fires are hot, smoky, and can reflash. Evacuate farther from the coach and keep people out of the path of the wheel in case of a blowout. Do not open the luggage bays. In both cases, the head count and the 911 call are the same, and you report the suspected source to responders.
